Single mode ZnO/Al2O3 Strip loaded waveguide at 633 nm visible wavelength

In this work, we proposed a technique in which two-dimensional (2-D) confinement of light is achieved in one-dimensional (1-D) planar waveguide by loading it with a low refractive index material. A waveguide design is based on ZnO/Al2O3 dielectric materials for integrated photonics. These waveguides are capable of propagating TE and TM polarization at 0.633 μm visible light. Based on these waveguide structures, many optical elements such as S-bend, Y-splitter can be realized which will provide a compact platform for integrated optics.
